Specification of Letters Patent.

Patented Nov. 18, 1919.

Application led March 25, 1915. Serial No. 17,035.

To all whom it may concern:

Be it known that I, HENRY L. Tirrnnr, a citizen of the United States, and a resident of South Dartmouth, in the county of Bristol and State of Massachusetts, have invented an Improvement in Cone-Tubes, of which the following description, in connectionwlth the accompanying drawings, is a specification, like characters on the drawings repre senting like parts.

This invention relates to cone tubes adapted to receive or have wound thereon yarn, thread or the like of the commonly known cone winding form and from which the yarn is drawn olf axially or substantially so. l

In certain aspects thereof,l my invention is an improvement upon that shown 1n the patent to Charles Gress, No. 986,379, dated March 7, 1911.

In order that the principle of the 1nvention may be readily understood, I have d1s closed; a single embodiment thereof 1n the accompanying drawing, wherein- Figure 1 is a side elevation of a cone tube embodying my invention; a

Fig. 2 is a vertical, central sectlon thereof;

Cone tubes adapted to receive or have yarn or thread wound thereon and from which said yarn or thread is drawn off axi ally when in upright position are customarily" formed of paper rolled in one or more layers or coils into conical form. TheseV tubes are adapted to be mounted for winding upon tapering arbors of thegeneral. shape of the tubes and extending through sald tube to within an inch on two of the tip end thereof. The ends of these conical tubes generally protrude somewhat from the complete yarn or thread mass. A cene tube of this general character but having an 1nturned apex end is disclosed in said Gess Patent No. 986,379, and I have represented theA disclosed embodiment of my invention as applied thereto.

Referring more particularly to the drawings and to the single embodiment of the invention here illustrated, the blank from which the cone or tube is formed is represented at 1 in Fig. 6, it being preferably of the segmental shape there shown. The said blank is coiled as indicated in Fig. 4 into a suitable number of contacting layers and the inner edges of the said layers should for the best results terminate substantially flush with each other, as indicated at 2 in Fig. 5.

Owing to the fact that the conical tubes are markedly tapering to facilitate the unwinding of the yarn or thread (such tapering materially exceeding that of the usual spinning spindle), it is exceedingly important in effecting the best results that such cone tubes be superficially roughened, thus preventing the slipping or displacement of the yarn or thread as the first series of layers thereof are wound uponthe tube and subsequently. This tendency to displacement, particularly of the first laid layers, exists to a marked degree in a cone having a decided taper, but it is nevertheless of importance that the cone tube and the yarn package woundlI thereon be of decided or markedly tapering form. Such roughening may be of any suitable character, though preferably it is effected by providing the cone tube with longitudinal ridges 3 inclined from top! to bottom, such roughening being effected either prior or subsequently to the ceiling of the pc per or other material into tube form, but preferably While thematerial is in its flat form. If as prepared'the cone tube be superficially roughened, the roughened portion is removed from the tip portion of the tube which, as stated, should present no obstruction to the unwinding of the? yarn or thread and especially to the unwinding of the first laid layers thereof.

In order to prevent the first laid coils or layers of the yarn or thread from contacting with the tip end of the cone tube as` they are unwound therefrom, the tip end 5 thereof is inturned or upset in any suitable manner, as rep-resented most clearly in Figs. 1, 2 and 5. The tip end of the cone tube should, for effecting the best results, be very materially inturned and preferably so as substantially, if not wholly, to close said tip end, and the inturned end may be turned into the cone tube to any desired extent so as to provide a downwardly extending edge portion. l

The tip end of the cone tube, as yarn or thread is being wound thereon, projects very materially beyond the tapered Vend of the supporting arbor. The approximate pov sition of the outer end of the arbor is indicated by the dotted line -sin Fig. 2, and is therefore free from contact with the said tip end of the cone tube. It is therefore possible to upset or inturn the tip end of the cone to a very marked 'degree and so as effectively to preventy the breaking or chafing of the yarn or thread by said tip end as the yarn or thread is unwound.

The cone is markedly conical in order to permit the yarn to free itself from the roughened surface when drawn from the end of the cone and is provided with stiff, cone supporting, side walls to sustain the usually large and heavy package. The tip end of the cone preferably is not only inturned but is smooth, the roughened surface of the body of the cone blending into the .,smooth, inturned surface of the tip. The

said in turned tip end is preferably indifferently centered internally with respect to the axis of the cone, this being possible because the tip end of the cone extends beyond the driver. This is a matter of practical importance, inasmuch as if, in manufacturing the cone, the apex end thereof be somewhat warped or distorted, the fact that the tip end extends beyond the driver permits it to conform in position substantially to the'driver, whereby the yarn or thread as drawn off will not be obstructed or impaired by said warped or deflected portion.

In order to prepare the tip end of the cone tube for the inturning action, I preferably first cut or slash the edge of the tip end in any suitable way, after which the tube is subjected to the described inturning action. Within the scope of my invention, this result maybeV effected in any suitable manner or by any suitable means, and for that purposel Imay e'ect the slashing or cutting by the same mechanism or by a portion of the mechanism by which the tip end is inturned.

In Figs. 7 and 8, I have represented the tip end of a cone tube before the same is inturned and have there represented it as having a series'of cuts or slashes 6 extending inwardly from the outer surface of the tube and Vwith a series of cuts or slashes 7 extendingl outwardly from the inner surface thereof and each extending partially through the walls of the cone. Such cuts or slashes may be of any suitable number, and preferably in forming them I remove a small portion of the material of such tip edge, thereby facilitating the subsequent inturning action. If desired, I may also cut or slash the tip edge of the tube wholly therethrough as indicated at 8, such cuts or slashes being preferably alternated with the slashes- 6 or 7 In -forming such cutsl or slashes 8, I may thereby remove portions of the substance of the wall of the cone. Preferably such cuts or slashes extend to a slight distance from the tip edge toward the base of the cone tube. Preferably subsequent to the cutting or slashing of the tip edge of the cone, I subject such tip end to an inturning action in any suitable manner. This may be effectively done by pressing the` tip end against a die, a movement of relative rotation being imparted to the cone tube and die, thereby to effect the described inturning action, and thereby twisting or circumferentially displacing the material, as represented at 9 in Figs. 1 and 3. So far as I am aware, I am the first to provide a cone tube having an inturned end, the latter .being cut or slashed or having matcrial removed therefrom to facilitate the inturning action, and therefore desire to claim the same broadly. The inturning of the tip end subsequent to the cutting or slashing of the walls thereof serves to cause contraction of the material at the said points of removal and the extent of the inturning may and preferably is such that at said cuts or slashes when the material is removed, the adjacent transverse edges are brought into contact, so that in the completed article there is presented a smooth tip end notwithstanding said preliminary cuts or slashes.

In accordance with my invention, I may, in addition to cutting or slashing the tip end of the tube, suitably reinforce such tip portion, and if this be done, I desirably accomplish this result by treating the tip portion with some suitable material, such, for example, as sizing or a proper amount of glue. Inasmuch as the tip portions of the cone tubes protrude somewhat from the formed packages, such tip ends are liable to become crushed or somewhat damaged during transportation. Such treatment of the tip end is preferably effected subsequent to the inturning action and after such treatment the cone tube is preferably polished, so that the completed cone tube has a slashed, inturned, treated, polished end, which not only presents no obstruction to the unwinding of the layers of yarn thread, but cannot readily be crushed or damaged in transportation. The sizing or treatment of the tipv end, if employed, may extend down to any suitable point.

l/Vhen the cone tube is in its normal con dition,-that is, before the tip end thereof has been inturned,-such tip end is substantially unyielding to inward pressure. When, however, the material of the tube has been circumferentially displaced, then the arch effect existing prior to inturning is materially lost and the twisted portions of the edge, because of their displacement,will more readily yield inwardly. This inturnA ing may be satisfactorily effected by subjecting the inturned end to the action of a die, the die and cone tube having a movement of relative rotation. Such relative rotation of the cone tube and die coincidently softens the material of the tip end portion, thus enabling it to be turned inwardly and to lie snugly in the die and to receive the smooth, highly desirable, polished surface. Such softening of the tip end renders such tip end less stiff and lacking in rigidity than the body of the tube, it being therefore more pliable and yielding than the body thereof. This, hovvever, renders thertip end liable to be crushed or damaged in transportation and to overcome this I treat the tip end as heretofore set forth and preferably by subjecting it to the action of some suitable material, such, for example, as sizing, by means of which such softening or yielding character is offset or neutralized. In adapting my invention therefore. to a cone tube having an inturned end, I preferably apply the stiffening material thereto after the inturning thereof has been effected, thus neutralizing, partially or Wholly, the softening action incident to the'inturning of such tip end.

rllhe sizing or other material is preferably so applied to the inturned end and subsequent to the inturning action that it neu `tralizes the softening of the end created by or incident to the inturning action, and therefore the finished cone tube With its inturned end is of substantially uniform stiffness throughout. If desired, I may apply the sizing or other stilfening material in such amount as to result in making the tip end of the cone| tube stronger than the body thereof.

The cone tube is preferably formed from a `segmental sheet of paper pulp, papier mache or other fibrous materialcoiled upon itself into a plurality of coils or turns.

Having thus described one embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of limitation, the scope of the invention being set forth in the following claims.
